Changed 1 action director: is not Chan Chuen, but Chang Chuang.

Removed 1 cinematographer: is not Lui Ming (who is an actor)

Changed production credits: Chan Wa is not exec. prod., but prod. manager.

Added 2 assistant directors, music, art dir., editor and 5 actors. Yuen Biao does not appear in the credits, maybe he does a very little role here.

BTW, second credit for Nam Chung-Il !
